Hrantvirus in Argentina: current situation and expert advice


Since the first known outbreak of Hantavirus pulmonary syndrome (HPS), in 1995 in El Bolsón and in 1996 in Bariloche some good things happened around the hantavirus in Argentina: Local and international experts in epidemiology and zoonoses studied the virus and its transmission vectors in more detail and thus documented the discovery of the Andes virus and human transmission. It has been possible to reduce the lethality of the disease – about 70% or 60% have fallen today to 40 or 30% -. But it was not enough.

Argentina and the United States – especially in the western area, California and Texas – are two countries with history around this Acute-contagion acute disease, which is transmitted by rodents carrying the family virus Bunyaviridae. Rodent infestations act as hosts for the disease to maintain persistent and asymptomatic infection. The hanta virus also arrived in Brazil, Chile, Panama, Paraguay and Uruguay in all cases of confirmed deaths.

Even this virus does not have a treatment or a specific vaccine to prevent it.
Whenever you know more about the habits and peculiarities of the long-lived mouse environment that not only lives in the Patagonian area; but the south of Argentina is dangerously endemic because it is the only area where the Andes strain is found that caused the latter Intermanent outbreak epidemic.

There are still many outstanding issues around the Hantavirus. According to the Commission on Endemic and Emerging Diseases (CEE) in the Argentinian Infectious Diseases Society (SADI), the characteristic – from December 2018 to January 2019 – of the unusual epidemic epidemic in the South is due to the suspicion of human transmission as a primary contagion. According to the last part of the nation's health secretary, aThere are currently over 28 confirmed cases across the country, of which 12 were fatal.

Areas compromised by hantavirus so far are to the north: Salta and Jujuy; Center: Buenos Aires (Lomas de Zamora and Garín), Santa Fe and Entre Ríos (Gualeguaychú); Northeast: missions and Sud, Neuquén, Río Negro and Chubut (Epuyén and Esquel).

Secretary of Health of the Nation, Adolfo Rubinstein He said about the cases presented in other regions of the country that "hantavirus is endemic in the country, there are annually reported 100 cases reported in the environment by strains other than the Epuyén epidemic which are being studied in the National Administration of Laboratories and Institutes of Health (ANLIS) Dr. Carlos Malbrán. "

In dialogue with Infobae, Dr. Daniel Stamboulian said about hantavirus, a subject that, as an infectious expert, continues long ago and was a key protagonist of 1995 El El Bolsón epidemic control with a group of North American scientists, "although Hantavirus infections have a low incidence for public health due to their mortality, the risk of outbreaks and the fact that there is no specific treatment available. Mothers and young people are most affected. "

Infobae He summoned two prestigious infectious disease physicians to review and specify up-to-date and up-to-date information. Specifying symptoms not only alerts the population, but also to the medical community to avoid underdiagnosis.

Transmitted and suspected infection

It should be noted that The epidemic of human epidemic is not the main way of infection. The most common route is through inhalation when breathing air contaminated by the virus removed from infected rodents.

Therefore, secretions and other human fluids should be considered potentially dangerous for the care of patients with hantavirus infection.

How to suspect it is Hantavirus? The first symptoms are similar to those of a picture of fever: 38C fever, muscle pain, nausea and vomiting, abdominal pain, asthenia, headache and diarrhea.

During its evolution, the infection can cause hantavirus (HPS) lung syndrome and hepatorenal syndrome with very poor prognosis and very high mortality. And detecting that during the six weeks preceding the onset of symptoms, the patient may be exposed to wild rodents.

In a dialogue with Infilios Lilián Testón, FUNCEI's infectious medicine specialist explained:SPH is a viral zoonosis characterized by fever, myalgia and gastrointestinal disorders, followed by a sudden onset of respiratory stress and hypotension. "

Although there is no drug specific for treatment, in front of these symptoms, supportive treatment should be initiated immediately: controlled water replacement and early assisted ventilation.

They are taken into account groups at risk of viral infection of rural people, tourists, campsites, guards, arrangers and cohabitants of the patient, as well as medical staff without adequate protection in the care of the patient.

Dr. Stamboulian strengthened Infobae"You have to ventilate before sleeping or staying in a cabin where there may be rats." Entry in closed tanks and tanks should be carried out with personal protective equipment: boots, masks, gloves, water cleaning and bleach. infection, the picture is similar to complicated pneumonia, heart failure, sometimes with kidney and coagulation disorders. Good intensive care is required".

As an effective prevention measure in endemic areas or for those traveling or traveling in the south, it is advisable to use N95 chinstrap and not to ground to avoid rodent bites.

As for the infected sick doctor Pablo Elmassian of Stamboulian Health Services and a traveler medical expert commented at Infobae, "If you travel to areas in the country that are compromised, you should avoid contact with the halls, camping away from them, as well as the dumps and weeds; for no reason sleep on the floor and always consume drinking water ".

The Secretary of Health of the Nation explained that ANLIS Dr. Carlos Malbrán is working in genomic sequencing of the virus, because it is very important to consider whether there has been a mutation that has increased transmissibility through inter-humanity, and also if you have to explore alternative therapies.
